Prune juice is from a long time ago and folks still like it today. Let’s learn more about it!

Does prune juice go bad?

Prune juice can get bad if not kept right. How long it stays good depends on how you keep it and if it’s open or not. When prune juice isn’t opened, it can last a lot longer. 

You can keep it for months past the date if it’s in a cool, dark spot. But when you open it, you need to be quick. Put it in the fridge and drink it in a week. This keeps it fresh and stops it from turning bad.

There are clues that tell you when prune juice is bad. It might smell weird, change colors, or get moldy. If you see any of these signs, throw it away. 

Don’t drink stuff that’s gone bad. To enjoy good prune juice, store it right and drink it up in time.

Prune juice can last a long time. It comes in two types: store-bought and homemade. Store-bought lasts longer because it has the stuff to keep it fresh. 

When it’s closed, it can stay good for months or even a year. Just check the date on the bottle. Keep it cool and safe from sun or heat.

Once you open a bottle, it won’t last as long. Drink it in 7–10 days and put it in the fridge. It might not taste as good, but it’s okay to drink.

Homemade prune juice doesn’t last as long. It doesn’t have the stuff to keep it fresh. Keep it in the fridge and drink it in 3–5 days. Put it in a tight container to keep it fresh.

If you want homemade prune juice to last longer, freeze it. Pour it into ice trays or boxes in the freezer. It can stay good for up to six months, but it might change a little when you thaw it.

How to Store Prune Juice

If you want to keep your prune juice fresh and yummy, follow these simple steps:

Keep it Cool and Dark

Put your prune juice in a cool, dark place like a cupboard. Don’t let it sit in the sun or near hot things like stoves. Keep it between 40°F (4°C) and 70°F (21°C).

Close it Tight

If it’s in a bottle or carton, always keep the cap tightly closed. This stops the air from getting in and making it taste bad. If you open the bottle, use a smaller container with a good seal.

Use the Fridge

After you open it, keep your prune juice in the fridge between 32°F (0°C) and 40°F (4°C). This keeps it fresh by stopping icky stuff from growing in it.

Freeze it

If you want to keep it for a long time, freeze it! Pour it into ice cube trays or special containers, but leave some room at the top. Put it in the freezer, and don’t forget to write the date on the container.

Thaw it Right

When you’re ready to drink it, let it thaw in the fridge or on the counter. Give it a good shake or stir to mix it up, and then enjoy!

Remember, these easy steps will keep your prune juice tasty and healthy for a long time!

How to Tell If Prune Juice Is Bad

It’s super important to check if prune juice is still good to drink. Old prune juice can taste yucky, feel weird, and maybe even make you sick. Let’s learn how to tell if it’s not good anymore.

Look at it

Fresh prune juice is dark brown or purple and kinda clear. If it’s got weird stuff like mold, lumps, or wrong colors, it’s bad. 

Smell it 

Good prune juice smells sweet and a bit tangy, like ripe prunes. If it smells bad, like something went bad, don’t drink it!

Taste it

Prune juice should be sweet and yummy. If it tastes sour, weird, or bad, it’s bad juice. Spit it out!

Feel it

Good prune juice is smooth and a little thick. If it feels grainy or too thick, it’s not good.

Check the date 

Look for the date on the bottle. If it’s past that date, it’s safer not to drink it. Dates help us know when things are best to eat or drink.

So, remember to use your eyes, nose, tongue, and hands to check if prune juice is still good. If anything seems wrong, it’s better to be safe and not drink it, okay?


To sum it up, prune juice can get yucky over time, just like other drinks. Things like air, light, and temperature changes can make it not good to drink. 

You need to look at the date, keep it in the right place, and use your nose and tongue to check if it’s not good. If you do all these things, you can still drink your prune juice and be sure it’s safe and tasty.


What is the shelf life of prune juice? 

The shelf life of prune juice varies but is typically around 6 to 12 months when stored in a cool, dark place. Always check the expiration date on the packaging for a more accurate estimate.
